Antenna tuning switch targets LTE-A smartphones

LISTED UNDER:

Peregrine Semiconductor Corporation announced a single-pole, single throw (SPST) antenna tuning switch for LTE-Advanced (LTE-A) smartphones. This device uses the company’s UltraCMOS process with its HaRP and DuNE enhancements to deliver a desirable combination of performance and integration to 4G wireless platforms. The PE613010 antenna switch delivers a low resistance-on (Ron) of 1.2 Ohms from 700 MHz to 2700 MHz. This maximizes radiated performance of the antenna in support of higher data throughput, increased battery life and longer range for fewer dropped calls, according to the company. The new antenna tuning switch is supplied in a miniature 2 x 2 x 0.55 mm package that requires zero external components. The PE613010 antenna tuning switch features high RF power handling and ruggedness, while meeting challenging harmonic and linearity requirements of LTE-A with Peregrine’s HaRP technology. With single-pin low voltage CMOS control, all decoding and biasing is integrated on-chip and no external bypassing or filtering components are required. The switch also features ESD tolerance of 2kV HBM on all pins, providing a monolithically integrated solution for tunable antennas.
